SILO.

Specification of Letters Patent.

Patented Nov. 3, 1914.

I Application filed .Tune 16, 1913. Serial No. 773,938.

To all whom it may concern: c

Be it known that I, GUsTAvE WENZEL- MANN, a citizen ofthe United States, and a resident of Galesburg, in the county of .Knox and State of Illinois, have invented a new and useful Silo, of which the following is a specification. I

My presentinvention relates to silos or similarly shaped structures which arev built Up of a plurality of independent sections and a plurality of independent vertically arranged standards interposed one at the adjacent ends of each section aforesaid.

One of the main objects is to provide novel exteriorly arranged means for locking the sections to each other and tensioning the silo, and employing the same means for locking the standards from displacement.

It is an object to provide a secondary lock for the same elements.

Another object is to provide certain novel structural features concerning the main and supplemental locking means. v

That the means for carrying out the objects above recited be durable, strong, simple and efficient is a prime requisite; to provide such means constitutes a further object.

That the several means employed are harmonious or correlated, and that they work to the same ultimate end, is an essential factor, and to provide such constitutes still another object.

The invention accordingly consists in the features and method of construction, combination of elements, and arrangements and disposition thereof for co-action, the scope of which will be pointed out in the appended claims. I

The accompanying drawings'illustrate a preferred embodiment of my inventlon.

In them: Figure 1 is a top plan, partly broken away, and one of the standards shown in section; Fig. -2,-a front elevation of the structure shown in Fig. 1; Fig. 3, a detail, seen from the end of a portion of one of the individual sections; Fig. 4, a detail, an enlarged front elevation of a fragment of a silo embodying my improvements; Fig. 5, a transverse sectional detail of a pair of strips and one of the dumb-bell connectors in operative position between them F g. 6, a longitudinal sectional detail; Fig. 7 a fragmental detail, seen fromran edgeof one of the standards; Fig. 8, a detail seen from an end of a vertical section; Fig. 9, an enlarged, modified detail, a front elevation,

seen as if turned on its end; Fig. 10, an enlarged, modified fragmental detail, seen from one end; Fig. 11, a perspective of the preferred type of stress-iron; and Fig. 12,

a perspective of the modification illustrated v in Figs.-9 and 10. I 1

Coming now to a detailed description of said drawing, in; which the same element and as well each feature thereof is, where expedient or necessary, uniformly designated bya distinguishing reference character, 2 designates either wedge shaped standard, of which there may be any suitable and preferred number and each of which may extend either the entire or, but

a portion of the length (or height) of the structure. As shown best at Figs. 1 arid 7, a portionat least of these standards may be in two pieces, 2, 2. The outer face of each standard is preferably curvilinear and projects slightly outward (radially) beyond the adjacent edges of the horizontally or flatwise laid wall strips 4, each of which as shown comprises an oblong block of wood having squared ends-the simplest and cheapest possible construction, as each strip Y or unit may be made from mill ends and .other least expensive material.

end of the strip. In longitudinal arrangement these grooves coincide with those in the standards 2 in order that a dumb-bell shaped link 7 may seat therein, as shown by said figures. ,A portion of the strips are provided each with a mortise 20 inits for a purpose presently recited.

18,8 designate a pair of stress-irons,;the

face,

rear edge of each of which is steppedat 11 to provide a ledge which rests on one of the projecting upper edges of a strip 4. Atits outer edge is a boss 12 having alongitudinally (or horizontally) arranged channel 13, Fig. 4, in which lies an endportion of a stress-rod 14 having threaded ends 15 which are engaged by nuts 14. 16, 16 are binding with a horizontally arranged groove 26 for the rod 14, and it is provided with an aperture for a bolt or screw 27 extending through its depth. At one end it is provided with an overhanging lip 28 and along its mid- 1- length, longitudinally arranged, are abutments 29, 30. 31 is a locking clip, one edge of which takes against the abutments 29, 30, and one end of which projects underneath and is locked by the lip 28, its other end be- ;ing locked by a nut'32 on the outer end of the bolt 27, for which last recited elements (3227) any other suitable securing means might be substituted.

The inclined strips 4 are effective in prewenting water running in the direction of the interior of the silo, as they provide a drain therefor.

hen the stress-irons are properly positioned in the mortises 20 the rods 14: may be L locked in the channels in the bosses 12 by the clips 16, whereupon the strips 4L may be drawn extremely close against the standards 2 by tightening eitheror both nuts 18 on the threaded ends thereof, as will be unllderstood from inspection of Fig. l. Any

individual portion may be thus tightened, and should adjacent strips in the same tier be secured thereto in any of the common modes, all such strips will be likewise drawn up. When the outer binding means is removed, or when for any reason the same is absent, the body elements will be locked by the link '7 in the grooves 3, which provides a secondary look. A structure built of ad l'jacent sections of superposed strips, even though the standards be omitted, would be locked together by either the stress-irons and their connecting rods or by the links 7.

It has not been thought necessary to encumber this specification and the accomg panying drawings with descriptions a-nd illustrations of additional modifications which are neither essential to nor form any part of the invention. In fact, it will be apparent without such changes may be made in the details of construction and by modifications involving merely mechanical skill, without departing from the spirit and scope of the invention, viewed in its broadest aspect. All this will be indicated in the claims hereof, wherein the omission of an element or the non-inclusion of detail features of the elements recited is intended to be a formal declaration of the fact that the omitted elements are not essential to the invention covered by that claim.

Therefore without limiting myself to particularities, I claim as new and desire to secure by Letters Patent the following, to-wit:

1. In a silo, a silo body composed of vertically arranged sections, stress-blocks secured one on each'of adjacent pairs thereof and arranged in the same horizontal plane, each of said blocks provided with a groove, a rod adapted to engage the grooves in both blocks, clips engaged one with each block andadapted to hold said rod within said grooves, and means engaged with said rod whereby said blocks and thereby said sections may be drawn toward each other.

2. A stress-block for silos, comprising a stepped base portion and its front portion provided with a groove and an overhanging that numerous lip, a clip one end of which is adapted to be restrained by said lip, and means for securing the other end of the clip to close the groove.

3. A stress-block for .silos, comprising a base portion and its front portion provided with an overhanging lip and an abutment arranged at a right angle thereto, and provided also with a longitudinally arranged groove, a clip one end of which is adapted to be restrained by said lip, and means for securing the other end of said clip to close said groove, one edgeof said clip adapted .to take against said abutment.

In testimony whereof I hereunto afliX my signature this 11 day of June, 1913, at Galesburg, Illinois, in presence of two subscribing witnesses.

IVitnesses:

L. F. IVERTMAN, F. L. CONGER.
